Abstract: The paper presents a review of some numerical technologies for investigation of shock wave and detonation processes in suspensions of gas and reactive particles in the frame of mechanics of heterogeneous media. Corrections of the TVD-schemes for fine-dispersed (in the frame of one-velocity two-temperature approach) and ultra-fine (equilibrium in velocities and temperatures) mixtures are introduced. The data of testing calculations and some results of numerical modeling of cellular detonations (on the model of aluminum suspension) are presented. A technology of parallel computations of detonation based on geometric principles is described. Linear dependence of acceleration on number of processors used is obtained in calculations on the complex MVS-1000.
